    • There are four screws with springs on them which have to be removed in the order embossed on the heatsink. (red circles)

    • Also make sure to unplug the fan very carefully. (pink rectangle)

    • Remove the heatsink by lifting it out to the left side as it is fixed on the right side.

    • The cpu DIE lies bare in front of you - this is a very sensitive part. This is why the heatsink is screwed on in a particular order.

    • Both the cpu DIE and the copper part of the heatsink should be cleaned as the thermal paste tends to dry out over time.

    • Use a cotton swab with some rubbing alcohol.

    • Never use a screwdriver or anything hard that might damage or scratch the surface.

    • Use thermal paste of your liking and apply a thin layer (I almost used too much).

    • The thermal pad (red circle) should not be replaced with thermal paste. If it seems dried out you have to use one of the same size.

    • Reattach the heatsink very carefully and tighten the screws in the given order. Also don't forget to connect the fan.

    • If your fan seems to be clogged with dust you should clean it while it's removed.
